Several different materials are available, and each material has advantages and disadvantages.
Dental fillings can be categorized as direct or indirect restorations. Direct restorations are fillings that get inserted into a cavity in a single visit. These substances include consisting of amalgams, ...

The problem is to test, based on the level of mercury, whether the two batches, X and Y, originated from the same catch. The statistical method used to perform this kind of test is the Mann-Whitney U-test.
Mann-Whitney U-test is used to compare whether two independent samples have been drawn from a population with the same characteristics. And it is used only when there are two samples to compare. In case there are two independent samples, Kruskal-Wallis test is used to investigate whether the samples were drawn from the population with similar characteristics.

The following steps would be followed when doing a Mann-Whitney u-test:

Meissner effect is one of the remarkable properties of superconductors. Most superconductors are metals and metal alloys. However, some non-metals also exhibit superconductive properties hence they are regarded as superconductors. A superconductor refers to a material that can transfer electric current with zero resistance. This implies that when electric current is passed through a superconductor at a temperature below the critical temperature value (Tc), no energy is lost in any form: sound, heat, or light. It is important to point out that superconductivity of a material can only be observed at temperature below the critical temperature (Tc). Critical temperature ...

Introduction
The vaccine-autism controversy came into limelight in 1998 after a UK-based gastroenterologist Dr. Andrew Wakefield published a paper linking the MMR vaccine to autism using inappropriate and false research techniques (Gerber & Offit, 2009). The theory was later disproved. Yet, some parents still felt that the reason for their child having autism was vaccine. This is primarily because the human mind is inclined towards reasoning, questioning and pattern perception. As Chabris and Simons point out in their book, this very drive for stamping on reasons for every occurrence and coincidence leads to the Illusion of cause theory (2010). According ...

Development, industrial and residential is an aim in sought by cities in their development aims.

Blood pressure is a principal vital sign that is examined by physicians. This is the pressure that circulating blood exerts on the walls of the blood vessels (Irwin & Rippe, 2008, Pp. 132). There are normal ranges of blood pressure, ranges upon which assessment is done so that blood pressure figures above or below signify an anomaly in the body systems (Criner, Barnette & D'alonzo, 2010, Pp. 187). As such, it is important for healthcare providers to be knowledgeable on how to assess blood pressure. This essay is a reflection on a skill learnt in the lab skills on how to ...

Externality is a situation in which the activity of one entity affects the welfare of another entity in a way that is outside the existing market (Rosen, 2005, p. 47). Simply put, externalities are the costs or benefits that arise from market transactions which are not reflected in prices. And when we speak of negative externalities, obviously, these are costs to third parties (other than the producer and consumer). Why is there negative externality? I learnt from Economics that under a competitive system, the market price of a good takes into account both the negative and positive effects of ...

Abstract

The experiment aimed at explaining the interaction of the molecules at different pressure, temperature and volumes. At low temperatures, the volume of the gas was low while at high temperatures, the volume of gas increased. The experiment successfully determined the value of absolute temperature using the Charles’s Law as 202.75OC which was lower than the theoretical value. The experiment also successfully verified the Boyle’s Law. The interaction of temperature and the volume of the fluid can be concluded to be directly proportional with an increase in temperature leading to increase in volume. On the other hand, the ...
